Deregulated miRNAs participate in osteosarcoma genesis. In this study, the expression of miRNA-218 in human osteosarcomas, adjacent normal tissues and Saos-2 human osteosarcoma cells was first assessed. Then the precise role of miRNA-218 in osteosarcoma cells was investigated. Upon transfection with a miR-218 expression vector, the proliferation of Saos-2 human osteosarcoma cells determined using the ATPlite assay was significantly suppressed, whilw migration of Saos-2 cells detected by wound healing and invasion determined using transwells were dramatically inhibited. Potential target genes of miR-218 were predicted and T-cell lymphoma invasion and metastasis 1 (TIAM1) and matrix metalloproteinase 2 (MMP2) and 9 (MMP9) were identified. This was confirmed by western blotting, which showed that miR-218 expression inhibited TIAM1, MMP2 and MMP9 protein expression. Collectively, these data suggest that miR-218 acts as a tumor suppressor in osteosarcomas by down-regulating TIAM1, MMP2 and MMP9 expression.

“…It has been reported that several miRNAs were misregulated in osteosarcoma tissues or cells, such as miR-34, miR-21, miR-140, miR-223 and miR-195 (He et al, 2009;Song et al, 2009;Wu et al, 2011;Mao et al, 2012;Li et al, 2012;Zhao et al, 2013). For instance, expression of miR-34s was decreased in tumor samples, and MiR-34 genes underwent minimal deletions and epigenetic inactivation in osteosarcomas ).…”

“…At the molecular level, RECK (reversioninducing-cysteine-rich protein with kazal motifs), a tumor suppressor gene, was a direct target of miR-21 (Wu et al, 2011). Moreover, microRNA-195 was shown to suppress osteosarcoma cell invasion and migration in vitro by targeting fatty acid synthase (FASN) (Mao et al, 2012). Therefore, miRNAs expression has a key role in regulating cellular processes in osteosarcoma, which need to further investigated in the future.…”

MicroRNAs have been demonstrated to regulate proliferation and apoptosis in many types of cancers, but biological functions in osteosarcomas remain relatively unknown. Here, we found expression of miR-802 to be up-regulated in osteosarcoma tissues in comparison with adjacent normal tissues. Enforced expression of miR-802 was able to promote cell proliferation in U2OS and MG63 cells, while miR-802 antisense oligonucleotides (antisense miR-802) inhibited cell proliferation. At the molecular level, our results further revealed that expression of p27, a negative cell-cycle regulator, was negatively regulated by miR-802. Therefore, the data reported here indicate that miR-802 is an important regulator in osteosarcoma, our findings contributing to a better understanding of important mis-regulated miRNAs in this tumour type.

“…Similar observations have been reported in a number of cancer cells. [37][38][39] The expression of CARM1 can be regulated by miR-15a and miR-181 in acute coronary syndrome and human embryonic stem cells reported by two groups, respectively. 22,23 However, no studies have yet examined that CARM1 is a direct target of miR-195-5p in colorectal cancer.…”

Coactivator-associated arginine methyltransferase 1 promotes cell growth and is targeted by microRNA-195-5p in human colorectal cancer

The pathogenesis of colorectal cancer remains poorly understood. Here, we show that coactivator-associated arginine methyltransferase 1 is frequently upregulated in colorectal cancer tissues and promotes cell growth in vitro and in vivo. Using bioinformatics-based prediction and luciferase reporter system, we found that coactivatorassociated arginine methyltransferase 1 is post-transcriptionally targeted by microRNA-195-5p in colorectal cancer. Ectopic expression of microRNA-195-5p led to the suppression of the coactivator-associated arginine methyltransferase 1 3′-untranslated regions activity and downregulation of the endogenous coactivator-associated arginine methyltransferase 1 protein in colorectal cancer cells. Expression analysis verified that microRNA-195-5p was markedly downregulated in human colorectal cancer tissues, which was negatively correlated with the elevated levels of coactivator-associated arginine methyltransferase 1 protein. Enhanced levels of microRNA-195-5p in colorectal cancer cells resulted in a sharp reduction of cell proliferative and colony-formative capacities in vitro. Remarkably, restoration of coactivator-associated arginine methyltransferase 1 in microRNA-195-5p-transfected colorectal cancer cells partially abrogated the inhibition of cell proliferation and colony formation mediated through microRNA-195-5p. These data confirm that microRNA-195-5p might function as an anti-tumor microRNA in colorectal cancer exerting critical control over coactivator-associated arginine methyltransferase 1 expression. The newly identified microRNA-195-5p/coactivator-associated arginine methyltransferase 1 axis may act as a novel promising therapeutic target for colorectal cancer treatment.
